§ 02 / About this part
What it is
The RICK'S MOTORSPORT ELECTRIC STARTER BRUSH PLATE REPAIR KIT, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Restore the electrical integrity of your starter motor with this brush plate kit. It houses the brushes and springs that power the armature. Wear on these parts is inevitable after repeated heat cycles and heavy use. This kit matches multiple OEM references including 21039-0004 and 31203-MEW-921. Rebuilding the motor housing is a standard workshop task for high-mileage bikes. Ensure the internal magnets are secure while you have the casing open for this install.

§ 05 / About Iron Offroad
Iron Offroad
Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
